Pomegranate

Pomegranates grown from cuttings or grafted stock often begin flowering within two to three years and setting fruit shortly after. They need long, hot summers to ripen fruit properly — in cooler climates, grow against the hottest, sunniest wall you have or in a large container that can be moved to a conservatory. Self-fertile, so one plant is sufficient, but a second improves yield. The ornamental scarlet flowers are spectacular even if the fruit does not ripen. Dwarf varieties like Nana are good container plants for conservatories.
